NEW YORK, Sept. 11 (Xinhua) — Emma Raducanu from Britain grabbed her first Grand Slam title by defeating Leylah Fernandez of Canada 6-4, 6-3 on Saturday in the U.S. Open women’s final.

The 18-year-old qualifier became the first player in the professional era to come through the qualifying rounds all the way to a major title.

Raducanu, ranked 150th, also became the youngest Grand Slam champion since 17-year-old Maria Sharapova at Wimbledon in 2004.

“I knew I would have to dig deep. It was an incredibly difficult match but I thought the level was really high. I had to play some of my best tennis,” said Raducanu, who is also the first U.S. Open women’s champion not to drop a set since Williams in 2014.
